When the screening tests were compared in the first trimester, the mean PAPP-A level was higher in the control group than in the patient group (p=0.006). Free -hCG was also higher in the control group (p=0.024).

The early-onset form, requiring delivery before 34 weeks of gestation, is the most studied and the one for whom first-trimester screening tests are achieving increased sensitivities32–34. Nevertheless, owing to its heterogeneity, elusive pathophysiology, and the lack of specific markers, preeclampsia...

Question 1. A patient had a negative First Trimester Screen, h-hCG test result. What should be done next? A negative screen means it is unlikely the fetus has Down syndrome or trisomy 18. The first-trimester screening test screens only for Down syndrom
Based on these parameters, second trimester screening, sequential combined tests or NIPT can be recommended for pregnant women. Finally, since free βHCG MoM > 5 has importance only in high risk group based on the FTS results, we recommend using the calculated risk of FTS for further ...
